This doesn't reproduce for me with a nightly build of main at f34dedbf44a0 (approximately a week old commit) from https://apt.llvm.org This issue is unlikely to be fixed in 18.x branch, because it's almost out of support at this point, so you should check whether it reproduces on a relatively recent build of main branch.

I tried with the latest and got this error. I found a bug report in the rust site which says that this is a llvm problem. I see some references to llvm18.1 but here is what I have installed.

Well, it makes sense to embed a release version of LLVM in a release version of Rust toolchain. If you see only Rust toolchain crashing when Clang 19.0 is used, it's an indicator that this is fixed in 19.0 and hasn't propagated to Rust toolchain yet.

I have made a report with mozilla. They may be using a buggy version of llvm in their build.
